The invention relates to a roving machine and more especially to awool evener and drawing machine for the making of worsted yarn.

The primary object of the invention is the `5 provision of a machine of this character, wherein slivers of wool material will be drawn for the condensing of the same and twisted in a single operation so as to have the slivers condensed to the desired degree for the making of the yarn or roving, the machine in its construction an assembly being novel.

Another object of the invention is the provisionkof a machine of this character, wherein `the drawing for the condensing of slivers of woolv 'l5 of diiferent qualities and sizes can be had and at the same time the slivers twisted so that the same can be passed to bobbinsL for the winding of the yarn thereon, the drawing action of the machine being increased from one end to the other, that is, from the receiving to the delivering ends, and in this manner eiecting the proper condensing of the slivers which at intervals will be operated upon by combs for the straightening of the bers or' material making up the slivers while at the same time cohesion of the fibers of the wool will be assured.

A further object of the invention is the provision of a machine of this character, wherein adjustment may be had for enabling it to handle different lengths of stock and in the arrangement of the drawing mediums and combing'devices an `even sliver will be assured in the operation of said machine.

A still further object of the invention is the provision of a machine of this character, which is comparatively simple in its construction, thorou'ghly reliable and eicient in operation, assuring the grouping of varying steps in the handling of the stock for making rovingsfor spinning frames in a single operation for` the production of worsted yarns, automatic in the working of the same and comparatively inexpensive to manufacture. y

With these and other objects in view, the invention consists in the features of construction,-

combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

" In the accompanying drawings: p

Figure 2 is a view similar to Figure 1 looking toward the opposite side of the machine.

Figure 3 is a top plan view partly in section.

Figure 4 is a sectional View on the line 4 4 of Figure 3 looking in the direction of the arrows.

Figure 5 is a sectional View taken transversely 5 of the machine on the line 5-5 of Figure 3.

Figure 7 is an enlarged fragmentary sectional View on the line 'I-'I of Figure 6. l0

Similar referencel characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a frame of suitable construction 15 and proportions for supporting the several parts of the machine as herein described. The frame A has arranged at the top edges of opposite sides I0 thereof upstanding horizontally spaced bearing uprights or columns II in which are jour- 20 naled upper and lower drawing rollers I2 and I3, respectively, the axle Ill for each upper roller being accommodated in bifurcations I5 vertically opening through the upper ends of opposed columns or uprights II while the axle I 6 of each A25 lower roller I3 is xedly journaled in the said uprights or columns. Thus it does appear in Figures l, 2, 4 and 5 of the drawings that the axles I4 of these upper rollers I2 are susceptible of vertical displacement and coacting therewith 30 are resilient blocks I'I tting the bifurcations I5 above the said axles and adjustably clamped at I8 within the bifurcations so in this manner the upper rollers I2 are yieldably or resiliently journaled. The lower rollers I3 at their outer work 35 engaging peripheral surfaces are luted or corrugated longitudinally at I9 to assume grip upon the stock 2D operating between the upper and lower rollers I 2 and I3 in the working of the machine. The stock Zll is Wool slivers receivedby 40 the machineat the entrance end denoted at B and delivered from the said machine at the delivery end C, respectively.

Located between the uprights or columns II supporting the rollers I2 and I3 are timed por- 45 cupine or comb rollers 2l, having their axles 22 suitably journaled in bearings 23 built onto the sides I0 of the frame A, these rollers 2l being disposed for rotation in the same plane of rotation of the lower rollers I3 and are for comb- `50 ing action on the stock 2|] for the straighten- `ing and the cohesion of the slivers making up the said stock in the roving operation of the machine.

Disposed transversely of the frame A and suitably journaled therein is a rotary power shaft 55 24, in this instance having xed thereto a belt power wheel or pulley 25 for the driving of the said shaft while the latter at one side of the frame A is provided with a pinion 26 meshing with a large gear 21 constituting the master gear of a group or train of driven speed gears 28, certain of these being common to the axles I6 of several of the lower drawing rollers I3, which latter through gear connections 29 operate the companion rollers 2| next thereto, these gear connections 29 rotate the rollers 2| at a uniform rate of speed while the group or train of gears 28 drive the rollers I3 common thereto at increased speed with respect to each other.

Arranged at opposite sides of the frame A are driven shafts 30, these being suitably journaled parallel with each other and longitudinally of the frame and have gear connections 3| and 32 with the remaining lower rollers I3 and 2|, respectively, the gearing connections between the said shafts 30 and the said rollers I3 being such as to increase the speed of rotation thereof with respect to each other so that the drawing action set up by the rollers I2 and I3 throughout the length of thermachine will be gradually increased from the end B to the end C of the frame A. One of the shafts 30 through the gearing 33 is driven directly from the train of gearing 28.

The gearing 34 connects the shaft 24 with an auxiliary shaft 35 which is journaled at 36. Built in the frame A adjacent to the delivery end C is a vertical rack 3'I being disposed crosswise of the said frame and this rack carries a series of rotatable twisters 38, each having concentrically therein a twister eye 39. The twisters are of gear construction having peripheral sprocket teeth 4I) engaged by an endless sprocket chain 4I driven through chain and sprocket wheel connections 42 and 43, respectively, by the shaft 35. Coacting with the chain 4I is an idle sprocket wheel 44 and by chain 4| the twisters 38 are/'operated in unison with each other while the eyes 39 receive the stock 26 for the false twisting thereof prior to delivery of such roving from the machine. The axes of rotation of the twisters 38 are at right angles to the axes of rotation of the drawing rollers I3, the upper rollers I2 coacting with the latter being presser rollers for the stock to assure drawing activity of the lower rollers I3 in the working of the machine.

Correlated with companion lower and upper rollers I2 and |3 is a stripping and condensing roller 45, which is disposed transversely of the frame A and is adjacent to one of the porcupine or combing rollers 2 I, the upper presser rollers I2 being provided with resilient or rubber peripheral coverings 46.
